Our Srar

Our StarIts image is mesmerizing - out of this world - through a solar telescope...A star full of life, willing to talk to you, sometimes through its carefree fairies (prominences), dancing at the disk limbs or its black halos (sun spots) and serpentine figures (filaments), crawling on its surface making any observer gazing at them in awe...

A fascinating spectacle changing every day without repeating the magic of the previous day...This is what makes it a unique, worth observing celestial object by amateur and professional astronomers alike....

STRONGEST FLARE OF 2016: Departing
sunspot complex AR2565-AR2567 erupted on July 23rd, twice, producing
two strong solar flares in quick succession. The first @ 0211 UT
registered M5 on the Richter Scale of Flares. The second @ 0516 UT registered M7.6, making it the strongest flare of 2016 so far: Credit Spaceweather.com

OUR STAR....

Thestar around which the Earth revolves, and the gravitational center of theSolar System; it lies about 270,000 times closer to us than the next nearest star. The Sun is a solitary, yellowdwarf star ofspectral type G2 (see G star) that has been on the main sequence for about 4.6 billion years.

The Sun consists largely of hydrogen (71% by mass) and helium (27%), with much smaller amounts of heavier elements. It puts out 400 trillion trillion watts of energy, produced by the fusion of hydrogen to helium by the carbon-nitrogen cycle in its core. The Sun is 109 times wider than the Earth. It spins on its axis with a period that varies from 25 days at the equator to 33.5 days near the poles.

PROMINENCES

Paradoxically, prominences are cooler than the surrounding atmosphere. They are columns of sun-stuff trapped and held up in the magnetic fields above the solar surface. The trapped plasma cools, recombines into hydrogen atoms and then emits visible light to show up as a prominence. The glowing gas twists and swirls in the sway of the magnetic fields and can change its appearance from minute to minute
